Comment (by ekohl):

 It is slightly inconvenient that at least for ovirt-engine there are
 branches and tags with the same name.

 That said, a start:

 {{{
 #!sh
 CHANGE_ID=$(git show | awk '/Change-Id:/ { print $2 }')
 if [ -n "$CHANGE_ID" ] ; then
     CONTROLLER=$(git symbolic-ref --short HEAD | sed
 's|^heads/\(.\+\)\.[0-9]\+|\1|')
     CONTROLLER_BRANCH=$(git rev-parse --verify --verify origin/$CONTROLLER
 2> /dev/null)
     OUTPUT=$(git log ${CONTROLLER_BRANCH:-master} --oneline --grep
 ="Change-Id: $CHANGE_ID")
     if [ -n "$OUTPUT" ] ; then
         echo "Change-Id $CHANGE_ID found in $OUTPUT"
     else
         echo "Change-Id $CHANGE_ID not found in
 ${CONTROLLER_BRANCH:-master}!"
         exit 1
     fi
 else
     echo "No Change-Id found"
 fi
 }}}

 It needs a check for {{{Label: $BRANCH-only}}} and I'm not yet sure how we
 reliably check all commits are valid without checking all commits every
 time. Maybe we can use {{{git log master..HEAD}}}, or was it {{{...}}} for
 the strictly only in HEAD but not in master?
